Abstract: Abstract A dispenser package for holding a stack of nested tapered disposable cups and dispensing them individually.  The dispenser package has a generally circular opening in the top wall through which the bottoms of the tapered cups protrude; the opening is surrounded by a series of short radial slits or knife cuts defining a series of yieldable tabs around the periphery of the opening which permit the topmost protruding cup to be pulled through the opening, but which function to restrain the remaining cups in the stack. Additional slits or knife cuts in the top wall of the dispenser package extend from the opening in the top wall to each of the sidewalls at a point near each sidewall to permit loading a stack of cups through the top opening of the dispenser package without tearing of the top wall.

Abstract: ABSTRACT       A process is provided for heat treating steel in which each segment of a piece of steel is quenched in a quenching zone by directing the flow of a sufficient amount of a cooling medium against a surface of each segment to lower the temperature of the segment to a desired temperature while vaporizing substantially all of the cooling medium to create a vapor blanket around at least one surface of each segment so cooled.  In one embodiment, steel pipe is heated above its critical transformation temperature and then each longitudinal segment of the pipe is sequentially quenched by substan-tially simultaneously sending a sufficient amount of water against the inside and outside surfaces of each segment to reduce the temperature of the segment to within a pre-determined range while vaporizing substantially all of the water to create a steam blanket around the segment.  The steam blanket is then maintained on at least the inside surface of each segment in order to control the tempera-ture change of each segment until the pipe is subjected to further processing.  An apparatus for heat treating a steel pipe is also provided including a preheater for heating the steel pipe; feeding means adapted to feed the steel pipe at a variable rate from the preheater; a flow chamber into which the steel pipe is fed, the flow chamber being adapted to bring a cooling medium into contact with the outer surface of a segment of the steel pipe; and an internal feeder having an outside diameter less than that of the steel pipe and adapted to direct a cooling medium against a contoured surface of a plug.  The plug is of sufficient size to seal slidably the inside cross section of the steel pipe as it passes into the flow chamber.

Abstract: ABSTRACT OF THE DISCLOSURE      A device in which units being transported can be adequately secured for protecting those units from damage during shipment is disclosed.  A chock that engages and substantially conforms to the surface of the unit to be secured is utilized.  The paperboard chock can be utilized in numerous ways.  The paperboard chock can be used independently by inserting it between a rigid structure and the unit to be secured such that the chock actively engages both the unit to be secured and the rigid struc-ture.  Two chocks could be used together by inserting the chocks between two units to be secured such that the chocks actively engage the units and are flush with each other.  Various alternative schemes of use can be utilized by inserting a cushioning means against the chock to apply pressure to the unit to be secured.  The chock is comprised of contact elements and a support element.  The contact elements actively engage the unit to be secured and are themselves attached to the support element.  The support element engages a rigid or cushioning structure so as to apply force to the contact element which therefore applies force and thereby secures the unit being transported.

Abstract: Abstract of Disclosure Heater Manufacturing A system in  which a substrate having a number of longitudinally-extending patterns thereon is slit along longitudinally-extending parallel lines intermediate the patterns so that a longitudinally-extending portion between each pair of patterns may be removed.  The substrate, with the portion(s) removed, is then guided between plastic sheets, and the plastic sheets are sealed to each other along the area from which the substrate portion(s) has been removed and along the outside edges of the substrate.  The substrate is aligned relative to the slitter using a system that includes a fixed guide roll the axis of which is parallel to and spaced from the slitter and a second guide roll mounted so that its axis is rotatable relative to the axis of the fixed roll in a plane parallel to and about an axis perpendicular to the axis of the fixed guide roll.  A sensor intermediate the fixed and second guide rolls senses the transverse position of substrate passing from the second guide roll to the fixed guide roll, and rotates the second guide roll to shift the substrate transversely when transverse misalignment is detected.  The gaps in the slitter and guide through which the substrate passes are only slightly thicker than the substrate so as to prevent wrinkling.

Abstract: ABSTRACT OF THE DISCLOSURE   A jalousie-type window with integral alarm circuit is disclosed.  The alarm circuit wiring is completely enclosed within the window construction and includes positive and negative terminals connected respectively to the louver blades and to the shafts which rotate the blades between open and closed positions.  An insulating air space is provided between each blade and its center shaft to prevent normally any flow of current therebetween.  Any attempt to force the louver blades of the jalousie open will result in the completion of the electrical circuit by causing the blade to deform through the air space so that contact with the center shaft is made.  The switch contacts of the circuit consist of a rectangular tube provided along one edge of each louver blade, and a rectangular center shaft housed within the tube, the rotation of which by a conventional turning mechanism causes the blades to open and close.  Under normal operating conditions, electrical contact between the two switch points is prevented by insulating nylon separators located at the ends of each blade and interposed between the tube and the shaft.  When any of the blades is forced open, the torque applied to the blade will deform the blade and cause contact between the blade tube and its associated center shaft to thereby complete the alarm circuit and cause the burglar alarm device to sound.
